Abstract

Un mode de réalisation illustratif dun procédé mis en uvre par ordinateur pour estimer une fragmentation de tas en temps réel modélise une vue dexécution de la mémoire de tas libre, modélise une vue dexécution de motifs dallocation de tas pour la mémoire de tas et prend une copie instantanée de la mémoire de tas. Un simulateur du dispositif dallocation de lot est exécuté à un événement prédéterminé et une quantité restante de la mémoire non utilisée dans la simulation est déterminée en tant que mémoire fragmentée.
